Study of alpha cluster structure in Mg-22

Abstract

The alpha-cluster structure in the nuclei has been investigated for the perspective of nuclear structure. Contrary to the case of the 4N nuclei with N = Z, the experimental evidences of the clustering structures for the proton-rich systems are still lacking information. In order to study the interesting proton-rich Mg-22 radionuclide, the Ne-18(alpha,alpha)Ne-18 elastic scattering will be measured at the Center for Nuclear Study Radioactive Ion Beam Separator of the University of Tokyo. By comparing the experimentally-obtained excitation function with theoretical R-matrix calculations, the resonance parameters of the Ne-18+alpha system will be provided in the energy range similar to 1MeV < E-c.m. < 12.4 MeV.
